Essential oil from the aerial part of Siberian wild and cultivated Artemisia dracunculus L. (AD, tarragon) was studied previously by GC–MS. The main components were identified as methylhavicol, 1-phenyl-2,4-hexadiyne, spatulenol, and caryophyllene-oxide [1]; from Italy, essential oil contained the main components estragol (70.1%), caryophyllene (14.3), and trans-ocimene (9.4) and was highly active and inhibited aggregation of erythrocytes [2]; from Iran, the main components were anethole (21.1%), -trans-ocimene (20.6), and limonene (12.4) and sedative and anticonvulsive effects were observed [3]. Essential oil from raw material from China contained the main components 3,7-dimethyl-1,3,7-octatriene (38.4%), -pinene (37.0), and 1-methoxy-4-(2-propenyl)benzene (8.6) [4]. According to various researchers, the main components of essential oil from this sage species are estragol and methylhavicol [5–8]; elemicin (50%) and methyleugenol (17.6%) [9]; methylhavicol and methyleugenol [10]. Sabinene (37-85%) and myrcene (8–10) dominated in oil obtained from Kazakhstan raw material [11]. The principal components of A. gmelinii Web. (AG) according to the literature [12] were artemisia ketone and cineole. The composition of oil from various natural populations and introduced species has been studied in detail [13]. According to this study, the principal components of AG essential oil were yomogi alcohol (up to 24%), 1,8-cineole (up to 32), camphor (up to 40), borneol (up to 24), artemisic acetate (up to 20), and chrysanthenylacetate (up to 73). The compositions of essential oils from A. marschalliana Spreng. (AM), A. proceriformis Krasch. (AP), and A. armeniaca Lam. (AA) have not been reported. Raw material for the studies of AD and AP was collected near Yntymak reservoir in Karaganda Oblast on June 15, 2001; of AM and AG, in Karkaralin Region of Karaganda Oblast on June 16, 2001; of AA, in AO SPC Fitokhimiya botanical garden on June 14, 2001. All samples were collected during budding. Samples were identified (Nos. 1999.09.01.02.07, 1984.08.00.02.01, 1996.09.01.02, 2001.06.16.01.04, and 2001.06.16.01, respectively) and preserved in the herbarium voucher of AO SPC Fitokhimiya. Essential oil was obtained from dried and ground aerial parts of the plants by steam distillation in a Clevenger apparatus for 2 h. The yields were 0.2% for AD; 0.2, AM; 0.4, AG; 0.42, AP; and 0.17, AA. GC–MS analysis of essential oil was performed under conditions analogous to those previously reported [14]. Table 1 lists the identified components and their percent content. Table 1 shows that the principal components of AP essential oil were -thujone (66.3) and -thujone (23.4); of AA, spatulenol (30.5), limonene (7.7), and -elemene (6.9); of AD, sabinene (20.2), trans-3(1-butenyl)isocoumarin (10.3), terpinen4-ol (8.7), and myrcene (6.2); of AM, 1,8-cineole (13.5), camphor (9.8), -thujone (5.7), and artemisia ketone (4.4); of AG, 1,8-cineole (28.5), camphor (11.3), borneol (9.3), and -thujone (8.6). Thus, the component composition of five sage species growing in Kazakhstan was investigated. The essential oil compositions of AM, AP, and AA were studied for the first time.
